inserting PDF object into powerpoint 2007 slide

one of my users is trying to insert a PDF page into power point slide but when she selects the object button in the insert menu (or ribbon) she receives a error message: "The server application, source file, or item can’t be found, or returned an unknown error. You may need to reinstall the server application". She gets this message just by clicking on the button, did doesn't even allow you to try to insert the document it just goes straight to the error message. What does it mean and how can i resolve this?

So it isn't related to PDF or something else!
The MS Powerpoint has problems itself!
Use Microsoft office "Diagnostics tools" from office button.
Or alternatively:
Repair the installation via "Add or remove programs" in control panel.
